To set up an Snmp Agent application

When you add an SnmpNetwork object, a Local Device component comes with it.

Right-click the SnmpNetwork node and select Views > AX Property Sheet.
The Enabled property should be set to true. If not, tick the option to true.
Set the Snmp Receive Requests property to Enabled (can send traps). This allows the Local Device to receive outside request messages from external Snmp sources and to send trap messages.
Set the Default Network Manager Ip Address property value to the address of your Supervisor host platform.
Set the Default Network Manager Snmp Version to 3.

NOTE: When you set the version to 3 in SnmpDeviceand click Save, some times the screen does not automatically reload so it may be necessary to refresh the screen.
